Google Wallpaper Picker

Until now many devices, especially Nexus, had their own internal apps for managing wallpapers – basically a simple slideshow of images to choose from. With Android 7.0 this app has changed and can now be installed externally on any device regardless of what model it is. Google Wallpaper Picker lets you choose from hundreds of wallpapers that download automatically once you select them. This means the app itself doesn't include the wallpapers, but requests them when you want to use one. You can even automatically download a new one every 24 hours. The wallpapers are organized by themes, including bird's-eye-view landscapes, minimalist geometric compositions, and much more. And it still lets you use any image you have stored locally on your device as well.
